1'0 all whom it may concern.-

Be it known that I, New AHRBIN, a subject of the Kin of Sweden and Norway,-residing at New ork, in the county of New York and State of New York, have invented certain new and useful Improvements in Apparatus for Vulcanizing Rubber Tires, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for vulcanizing rubber tires: and the object thereof is to provide an improved apparatus oft-his class which is particularly designed for use in the repairing of rubber tires or in vulcanizing parts of a rubber tire in the-operation of repairing the same, a further object being to provide an apparatus of the c ass specified which is adapted for use in repairing and vulcanizing rubber tires of different sizes in transverse section; and with these and other objects in view the invention consists in an apparatus of the class specified constructed as hereinafter described and claimed.-

The invention is fully disclosedin the following Specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are desi nated by suitable reference characters in eac of the views, and in which-- Figure 1 is a perspective view of my improved apparatus and showing the parts thereof in an open position; Fig. 2, a transverse section on the line 2 2 of 3 and showing the parts in a closed position; Fig. 3, a plan view of the apparatus as shown in Fig. 2 and Fig. 4 a partial section on the line 4 4 of Fig. 2.

In the practice of my invention I provide a base member, frame, or support a, which 09mprises a horizontal top portion a, supported by legs a having transversely-arranged feet a, and mounted in the leg members a in the 7 form of construction shown is a gas-pipe b,

having an upwardly-directed nozzle b provided with a valve 1), having a-stem b, by

'member which it may be operated.

The operative parts of the apparatus are mounte above the base member, frame, or support a, andcornprise a main stationary jaw 0 ha acentral depending tubular. he lower end -'of which passes downwardly through the horizontal part a,

of the base member, frame, or support and recelves the nozzle 1), whichli's connected with the gas-pipe b. The main stationary jaw c is oblong in form and approximately semicircular in cross-section, and the inner side thereof is hollowed out to form a chamber or recess 0 and inwardly-directed end flanges c, and placed within the rhain 'sta tionary jaw c is a supplemental detachable jaw d, which is of the same general form as the main stationary jaw c and the front face of which is provided with a longitudinal segmental groove d above and below which are plain faces or face-plates (1 and the end of the supplemental detachable jaw d is pro- (1, which, taken in connection with the hollowed-out recess or chamber 0 in the main stationary jaw 0, forms a main gas-chamber c in the main stationary jaw c. The end flanges c and d of the main stationary jaw c and the supplemental detachable jaw d are so shaped as to produce between the said jaws and at the opposite ends thereof segmental slots or openings 0, which communicate with the chamber a and placed inthe bottom of the chamber a longitudinally thereof is a screen c, which covers a port or passage c, which forms a communication between the tubular member 0 and the chamber 0 and said screen serves'to distribute the gas throughout the said chamber 0, in which 1n the operation of the apparatus the gas is, ignited and burned.

Connected with the bottom ortion of the tubular member 0 above the aseframe or support a, are two parallel and horizontal members e, which are hollow or provided with longitudinal passages e, which communicate, b means of ports or passages 0, with the tub ar members, as clearly'shown in Figs. 2 and 4, and connected with the hinge ,members e is a main movable jaw f, which corres onds with the main 'statlonary jaw c and w 'ch is of the same eneral form as sand main stationary jaw c. he connection between the jaw f and the hinge members. e is made by meansof a central backward projection 0, formed on said jaw and which fits be vided with backwardly-directed end flanges tween the hinge members 3 and through which is passed a valve-tube e, which communicates, by means of ports or passages e,

with the passages e in the hinge members e;

The jaw f, as'hereinbefore stated, is of the same general form as the jaw-c and is provided with inwardly-directed end flanges and placed in said aw is a supplemental e tachable jaw g, which is of the same form as the jaw 11 and provided in the face thereof main gas-chamber f 4 into the which is a tive 5 c an lines.

to ether, as shown in screw h, and at one sid 5 5 clamp h a the free end of which is passed a screw h.

thmain movable jaw f,

.the to face-late vid "*witli 6 5 sscrews hand 7e",

with a longitudinal segment al groove 9 and l at the ends thereof with backwardly-directed segmental end flanges g and the flanges f 2 and g on the jaws f and 9 form a between the jaws f and l 'g, similar to the chamber 0 between the jaws 5 c and d and in the bottom of which is placed i a longitudinal screen 9. I The central backwardly-directed projec- 10' tion e forms a port or passage, which connects the jaw f with the hinge members e and is hollow, as shown in Figs. 2 and 4, and between said projection e and the chamber f 4 in the j aw f, or between the j aws f and g, is a I 5 port or passage 6, similar to the port or passage c and through which the gas is admitte and the tube e as I mitted into the chambers formed by the sta into the chamber f will be seen in Fig. 2, is provided with a port or passage 9,

inge member e From the foregoing description it will be seen that the parts e and (1, although described herein as main and supplemental jaws, form, in effect, a main stationary jaw, in gas-chamber having segmental slots or openings at its opposite ends, and the parts 9 and f, although herein, respectively, described as a main movable and supplemental jaw, form, in effect, a main movable o aw having a central gas-chamber similar to that in the main stationary jaw formed by through which the gas passes the parts 0 and d. 1

' In Fig. 1 of the drawings the main opera- (parts, formed, respectively, by the jaws d and jaws f and 9, connected as described, are shown in an open position, and

in Fig. 2 the said parts are shownin a closed 'POSitlOD, the movable parts or members being also indicated in an open position in dotted The main stationary jaw c is provided at the top thereof and centrally thereof with a yoke-shaped clamp 72, which is hinged thereto 8th and at the free end of which is a set- 45 screw 71?, adapted tobear on'a longitudinal flange h at the top of the jaw member f, and in this way the main operative parts of the apparatus comprising, respectively, the jaws c and d and the jaws and 9 may be locked ivoted at k and by the same ivot-pin that holdsthe yoke-shaped clamp ii is a dog h, through the free end of which is passed a e of the yoke-shaped is pivoted another dog h through which is placed in has top and bottom face-plates 9, similar to the face-plates d at and bottom ofthe jaw d, and the at the top of the jawd and the at the top of the jaw g are pro-. 'vertic'all arr'anged grooves 71,

The supplemental jaw g,

face-p ate (1 which are adapted to receive the ends of the carried bythe dogs h and h i, from which in practice a rubber tire may be suspended, and the operation of the apparatus as herein described will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statenient thereof. In practice the tire to be mended or repaired is suspended from the loop member if, and that part thereof to be vulcanized is placed in the roove (1 in the jawmember d, and the mova le jaw member comprising the parts f and g is swung into the closed position, as shown in Fig. 2, and locked therein. At this time the gas is adtionary and movable jaw-members consisting, respectively, of the parts 0 and d and of the parts f and g, and this gas is ignited through the end slots or openings 0 in said jaw members, and the said jaw members are heated to the required degree and the vulcanizing process is carried on as in other apparatus of this class.

The screws h and h are intended for use in case a tire is to be repaired at the point where the valve-nozzle used for inflating the tire is located, and when necessary either of 5 these screws may be turned down far enough to form in the tire the necessary opening, or the dogs that carry these screws may be tur led back out of' operative position, in which event, if-the tire is suitably provided with an air-valve nozzle, the said valve nozzle will fit in oneof the recesses 11, formed in the face-plates d and g of the jaw members d and g, and when the tire is to be mended or repaired at other points the screws k and 'h are manipulated, so 'as to fill the grooves or recess & and so that the inner ends thereof will be flush with the top wall of the se mental grooves d and g in the jaw mem ersd and g. j

In order to provide the apparatus with means whereby tires of different thickness or dimensions may be-repaired or mended and vulcanized, separate pairs of auxiliary jaws j are'pivoted or hinged to the o posite ends of the aw members 0 and f, as 0 early shown in Figs. 1 and 3, one pair of said being shown in position for use in Fig. 2. The only difference between the jaws j at the opposite ends of the apparatus is in the fact that one pair is thicker than the other, so as to adapt the apparatus to different thicknesses of tires, as hereinbefore described. It will be observed that the connection between the separate pairs of auxiliary jaws j and the jaw members 0 and is made by'means of projections j andf, ormed orconnected with the auxiliary jaws gafrts'jand c andf, the said projections 7' and 7 ormlng hinge members, connected at j in the usual manner, and the form and dimensions of the hinge membersis such that when the parts are in the open position, as shown in Fig. 1, the auxiliary jaw members '7' at either end of the apparatus may be s into position between the jaw members at an 9, 1t will be observed that the auxiliary jaw members j are made segmental in cross-section and resemble the half of .a pipe of equal length, and the length of said jaw membersj e same as that of the grooves d and g of the jaw members (1 and g, and when said jaw members at either end of the apparatus are swung into the operative position they only serve to decrease t-he diameter of the circular space formed by the grooves i1 and g in the jaw members d and g.

It will be observed that the apparatus may be used without either of the auxiliary jaw members j being swung into position, and in this event the diameter of the grooves d and g in the jaw members (1 and g'will fix the diameter of the tire tobe repaired or vulcanized, and when smaller tires are to be operated upon either set of jaw members j may be swung into position, as may be desired, and it will also be understood that the separate sets or pairs of jaw members 1' may differ in thickness to any desired extent.

The movable jaw member is also provided with a handle k, by which it may be manipulated or swung into its different positions, and any suitable means may be provided for holding the auxiliary jaw members 7' or the different sets thereof in the open position, so that they will not interfere with the operation of theapparatus when the use thereof is not required.

The auxiliary jaw members 1' or the separate pairs thereof are provided with pintle- 0 pins having handles 7' by which they may be easily manipulated, and the auxiliary jaws or the separate pairs thereof may be entirely detached, if desired or whenever desired, and locking-keys j are also preferably provided for holding the auxiliary jaws j in an open position; but any suitable means may be provided for this purpose.

This apparatus may be used for vulcaniz-' ing rubber tires of any kind or class, and especially in repairing such tires, and by means of the construction herein described tires of different sizes, as will be apparent, may be mended, vulcanized, or repaired, and my 1mproveinent is not limited to the exact construction of the various parts of my improved apparatus, and various changes in and mathfications' of the construction herein shown and described may be made without departmg from the spirit of myinvention or sacrific- 6o ing itsadvantages.
